Liz's name was read when Janine brought a BSA flier to Claudia and the rest of the BSC. She is first shown in physical appearance when the club found out that they were tricked by other BSA members by finding Liz with the members that "joined" the BSC. She was later shown with Michelle Patterson when they were scored by the members of the Baby-sitters Club. She tried to start a new job called Makeovers, Inc. as mentioned in the epilogue, but no one would join.
Liz's appearance is not shown in the books, but in the graphic novel version, she has tan skin, dark brown hair, and is often seen wearing a black coat with cheetah-printed fur, a pink shirt, and black pants.
